Step by Step Solution

Step 1. Given information.

The height and slant height of a regular square pyramid are 12 and 13 unit respectively.

Step 2. Write the concept.

The base edge is given by:

Base edge=2(l)2(h)2

And the lateral edge is given by:

lateral edge=(l)2+(base edge2)2

Step 3. Determine the values.

Substitute all the given values in the formula.

Base edge=2(13)2(12)2 [substitute]=2169144 [square]=225 [subtract]=10 [simplify]


Lateral edge=(13)2+(5)2 [substitute]=194 [simplify]
